First DocBook version.

This HOWTO is effectively obsolete, and
has been so since 2003. Current versions of X compute optimal
modelines from EDID information returned by your monitor. In addition,
many of the constraints and caveats in this document applied to CRTs
but no longer apply to digital flatscreens.

How to compose a mode line for your card/monitor combination
under X.org (originally
written for its ancestor
XFree86).
X distributions now include good facilities for configuring most
standard combinations; this document is mainly useful if you are
tuning a custom mode line for an ultra-high-performance monitor or
very unusual hardware. It may also help you in using
xvidtune to tweak a standard mode that is
not quite right for your monitor.
